ABSTRACT:
A cutter holder assembly for holding a cutting tool supported at a tool carriage moving in at least an X-Y plane and provided with a cutter for engraving an item to be engraved includes a mounting base capable of being fitted to the tool carriage, a holder base supported at the mounting base in such a manner as to be freely moveable along a Z-axis provided in direction of a prescribed straight line, and a cutting tool holder having a cutting tool support supporting the cutting tool and being fixed to the holder base. Rotation of the cutting tool holder about the Z-axis with respect to the mounting base is restrained and an angle of inclination θ constituted by an angle formed when a longitudinal axis of the cutter and the Z-axis intersect can be held at a prescribed angle. It is therefore possible to provide a cutter holder assembly for an engraver capable of implementing engraving technology capable of a variety of types of engraving of a wide variation without limitation at a part to be engraved.
